ROANOKE, Va. (AP/WFXR) — Opponents of the Mountain Valley Pipeline are gearing up for another legal fight as they try to stop the natural gas project.

The Roanoke Times reports that environmental and community groups filed a petition last week with a federal appeals court.

The groups want the court to review a decision made by the State Water Control Board earlier this month, which allowed the infrastructure to cross streams and wetlands.

The Sierra Club was among the groups that filed the petition with the 4th U.S. Circuit Court of Appeals.

Pipeline opponents say Mountain Valley should not be allowed to continue with the project, given the company’s past rack record of violating erosion and sediment regulations.

However, Mountain Valley says those problems were largely caused by heavy rain in 2018 and have been corrected.
